Keep the soil consistently moist but not waterlogged, especially during active growth. Treeferns thrive in humid conditions, so regular watering is crucial. In drier periods, increase frequency.

Ensure good drainage to prevent root rot.

Prune away any dead, damaged, or discolored fronds as needed. Cut these at the base of the frond stem. Avoid removing healthy fronds unless necessary for shaping or space. Pruning is minimal for healthy specimens.

Propagation is typically done by spores. Collect mature spores from the underside of fronds, sow them on a sterile, moist medium like sphagnum moss, and keep them in a warm, humid, shaded environment.

Germination can be slow.

Repotting is rarely necessary unless the fern outgrows its container or drainage becomes an issue. If required, use a well-draining, slightly acidic potting mix.

Repot in spring when new growth begins, handling the root ball gently.
